The standard Galaxy kernel based on a very old 2.6.27 version and their are lot of changes after this kernel. So i planed to upgrade the kernel to the version which used the N1 Google phone. I prefer to start from the Samsung update3, because it is the latest and i hope the wlan driver has the needed fixes.

I created a diff between the andoid-msm-2.6.27 and update3. The diff-file is 9mb big and shows that 800 files are different.

These subprojects must be ported to the new 2.6.29 kernel, also many other files:

arch/arm/configs
arch/arm/include/asm

arch/arm/mach-msm

Sometimes i need to see the system log from my android mobile. As root on android i can see this in the terminal with dmesg. But i want to see it on my desktop computer.

The Android SDK has the solution. Simple

The Dalvik Debug Monitor Service (DDMS) is a debugging tool. It is designed for  dalvik, the java based virtual machine used in Android. DDMS comes with the Android SDK. This sdk is only for 32bit platforms created, but most
